Dog Feed Indicator - Optimized Remix

I printed the original version, and thought it was very well done (thank you to the original creator). However, I wanted to make a few modifications.

Primarily:
- Text made bigger for breakfast/lunch/dinner
- Made the text "push" upward, instead of downward
- Removed the "feed" from the thumb slider, and made it an arrow instead (easier to print as it now no longer needs supports)
- Pulled the upper and lower bone structures down by about 1/2
- Increased the holes and decreased the pin sizes to make sure they fit nicer on more machines
- Gave more wiggle room to the slider, as the first layer could print too tight
- Added some internal bevels on the slider (so it sticks a bit less sliding it back and forth)
- Removed the original screw mounts
- Added more of a front-facing screw mount (so you can also hang it from a string)

It sounds like a lot, but 95% of the work was done for me by the original author. I think it turned out great - I used my FlashForge Creator Pro to dual print t
